This Privia Digital Piano Sounds and Feels Like the Real Deal!

Thanks to Casio's proprietary sound source, "AiR" (Acoustic and intelligent Resonator), the Casio PX-850 Privia digital piano is able to capture the true sound and resonance of an acoustic grand piano with impressive realism and detail, providing the dynamics, damper resonance, and natural attack and release that you would expect from true grand. This 88-key digital piano even simulates the sound of a grand piano lid being open or closed in varying degrees. How's that for realism?

What Sets This Privia Apart?

In a stylish cabinet that opens for a rich concert sound, the PX-850 offers 18 instrument tones -- 5 of which are pianos -- with 256-note polyphony, split and layer, a 2-track recorder, digital effects, a dual 20-watt speaker system, USB connectivity, and 3 pedals. The piano's built-in 20W quad-speaker system ensures that its ultra-resonant sound makes it all the way to the back of the room.

Sounds Driven by AiR

With Casio's PX-850, you'll have the option of playing not 1 great instrument, but 18. The 18 built-in tones -- along with digital effects like reverb and chorus, 60 preset songs, and 10 user song locations -- will keep every performance interesting.

Casio's AiR engine, designed to produce detailed dynamics and damper resonance, even compensates for the speed at which an acoustic piano's hammers strike strings at different velocities and key ranges. The Acoustic and intelligent Resonator engine does this using more than three times the waveform memory of Casio's previous generation of digital pianos. On this piano the capacity of the installed memory has been expanded to achieve a longer sampling duration and enhanced waveform data quality, and in turn, deliver the natural changes in tone that make a piano sound like a piano.

Natural-Sounding Damper Resonance

Just as you would on an acoustic piano, you can use this digital piano's damper pedal to add natural-sounding resonance and expression to your performance. Rather than using effects processing, the PX-850 employs a stereo resonance simulator installed on all 88 keys to achieve its deep resonant sound.

Keys that Please

In making the PX-850, Casio did its best to reproduce all qualities of an acoustic grand, tones and touch included, and put those features in a compact, affordable instrument that feels just as good as a real grand piano. The PX-850 boasts the Tri-sensor Scaled Hammer Action Keyboard II with simulated ebony and ivory keys, which provides a natural key response. It incorporates a system with three sensors that detect touches of the keys sequentially, for accurate timing that you can hear. A key-off simulator reproduces the tonal variations that result from releasing your finger from the keys.

Put a Lid on It!

Lid simulation takes the PX-850 beyond the capacity of most other digital pianos. On a grand piano, the sound volume and quality change when the lid is raised or lowered; the same goes for Casio's PX-850, as it simulates the acoustic effects of opening and closing the lid. You can choose whether you want the lid to sound like it's open, closed, half-open, or removed.

Record Song Ideas, Then Save Them

The PX-850's handy two-track recorder allows you to track your progress during practice time, as well as help you remember song ideas. Likewise, Duet mode allows the keyboard to be split into two equal ranges, so that student and teacher can play at the keyboard at the same time.

For convenient connection to recording and sound reinforcement equipment, the PX-850 sports 1/4-inch audio outputs and USB-to-Device output. You can move songs to and from a computer into the digital piano's flash ROM and save the songs you've created on the piano.

Casio PX 850 Privia Digital Piano

The flagship of Casio's Privia line, the PX-850's advanced AiR sound set provides an additional level of realism, including grand piano lid simulation and sympathetic resonance. The PX-850 has a dual 20-watt speaker system and a cabinet that opens providing a rich concert sound.

The Flagship

The PX-850 represents a significant step in the continuing evolution of the Privia digital piano line. A combination of a keyboard action and a powerful sound engine provide a high level of detail, nuance and expression for a superior grand piano experience in the lightweight and stylish design that Privia is known for. The PX-850 has 18 Instrument tones (5 are Piano), and 256 note polyphony. The PX-850 keys feature Damper Resonance, Hammer response and Sympathetic Resonance. Another feature to enhance the realistic feel of a grand piano is the lid simulation. You can choose (separate from what the actual PX-850 cabinet will do) whether you want the lid on the Grand Piano open, closed, half or removed. The PX-350 has 1/4" audio outputs and USB-to-Device output so you can easily connect the PX-850 to recording and sound reinforcement equipment.

Multi-Dimensional Morphing AiR Sound Source

The characteristics of Casio's Multi-dimensional Morphing AiR (Acoustic and Intelligent Resonator) Sound Source reflect thorough attention to detail in expressing the rich, resonating tones inherent to the piano. The capacity of the installed memory has been expanded to achieve a longer sampling duration and enhanced waveform data quality. The temporal changes in tone that create sound you would expect only from a piano, beginning with the initial sound and leading into a beautiful extension until the sound eventually vanishes, are reproduced naturally.

Keyboard System

Natural playing feel approaching that of a grand piano firm touch that converts the player's thoughts into sound. The difference between the sound structures of a grand piano and a digital piano appears as a difference in timing, from the moment the instrument is played until the sound is audible. The Tri-sensor Scaled Hammer Action Keyboard II responds by incorporating a system with three sensors that detect touches of the keys sequentially.

Simulated ebony and ivory keys with optimal fingertip fit for playing ease
The Simulated ebony and ivory keys offers the luxurious feel and texture as well as the smooth touch of a grand piano keyboard. The minutely detailed crimp surface finish inhibits finger slippage due to sweat and gives the sensation of a perfect fingertip fit, even when playing for extended periods.

Lid Simulator reproducing the sound effects resulting from an open lid
The sound volume and quality change when the lid on a grand piano is raised or lowered. The Lid Simulator reproduces the same acoustic effects for enhanced enjoyment with a digital piano. The acoustic effects of opening and closing the lid are simulated in fine detail. The piano sound you are seeking as you play is always available for your enjoyment by selecting the degree to which the lid is raised or lowered. The Lid Simulator setting value remains unchanged, regardless of whether the lid on the piano body is open or closed.

An Unprecedented Evolution of the Digital Piano

String Resonance* resonator achieving deep, rich resonance with 88 keys
The sound produced by an acoustic piano is not only the sound associated with the keys that are struck. Other strings with frequencies closely associated with those producing the sounds resonate as well, adding their sound to give the music a uniquely rich resonance. In ordinary digital pianos, this string resonance effect is reproduced virtually with strings. The Multi-dimensional Morphing AiR sound source takes a different approach, however, by adopting a "string resonance" system incorporating a stereo resonance simulator for all 88 keys. The resonance of the 88 keys is reproduced completely and naturally. The resonance realized by playing a single tone is differentiated from that realized by playing a chord to reproduce the resulting variations in resonance in a natural manner. This even enables players to achieve varying resonances, controlling them at will by the strength of their touch, and thus to realize performances with the unique expressiveness of an acoustic piano.

Key Off Simulator reproducing tonal variations resulting from finger release
The lengths of the reverberations and expressions a piano produces vary depending on the speed at which players release their fingers after touching the keys. The keyboard system incorporates a Key Off Simulator that reproduces these nuances resulting from key release naturally. Authentic reverberations that feel just like those of a grand piano are expressed as a result.

Damper Resonance. Achieving a more naturally beautiful resonanceThe deep, beautiful resonance resulting from the use of a damper pedal is also reproduced naturally by a stereo resonance simulator installed on all 88 keys, an approach that differs from conventional simulated reproduction employing effect processing. The attention to detail goes so far as to simulate the resonance created by the lifting of the dampers themselves when the pedal is pressed. A continuously variable system has been adopted for the damper pedal, moreover, reproducing even the subtle changes in reverberation that occur in response to the delicate pressure exerted by partial pedal operation. This enables players to employ pedal operation to achieve gracefully expressive performances.

"Wow!"

Overall:
I own a Yamaha Clavinova and it is a good piano. I purchased the Casio Privia 850 after reading great reviews on it and it is all true. The keys have an awesome texture, the sound is fantastic! It does sound a bit electronic and you will notice it only with your headphones on however the sound is amazing and it is loud without choking or creating distortion. It is big enough for a sit down but compact enough to fit anywhere. It is handsome. I was a bit hesitant because I owned a Yamaha and it was a good piano but the Casio sounds 100 times better. I recommend this piano! It is loaded with features!

Thank you. Your vote has been counted. Could you briefly tell us why the review was or was not helpful?
